CFexpress 4.0 Type A card for Sony cameras

The card is built to the CFexpress 4.0 Type A specification and carries VPG 400 certification for sustained video capture. It is engineered for Sony Alpha and FX bodies including the 1, 1 II, 7 IV, 7R V, 7 S III, 9 III, FX3, FX30 and FX6. Capacity is 512 GB.

Check camera slot and firmware before purchase

Verify that the camera accepts CFexpress Type A media and that its firmware is current enough to recognise the card. The card updates its own firmware through an Angelbird CFexpress Type A reader, so access to that reader is required for future compatibility fixes. No other host interface is supported.

Sustained 800 MB/s write with thermal management

Stable Stream Technology delivers a consistent 800 MB/s write rate across all recording modes rather than only in short bursts. Advanced thermal management protects the card and data from overheating during long takes, while minimal power draw preserves camera battery life. Maximum read speed reaches 1800 MB/s and maximum write speed 1650 MB/s.

Questions about this item

Does the 512 GB CFexpress 4.0 Type A card ship with a reader or must I buy one separately?

The card is sold alone; a CFexpress Type A reader is required for firmware updates and data transfer and is not included.

Why choose the 512 GB VPG 400 version over a smaller capacity?

The 512 GB capacity supports the VPG 400 sustained write guarantee needed for 8K+ RAW video on compatible Sony Alpha and FX bodies.

What does the 800 MB/s sustained write figure mean when recording in camera?

It guarantees a minimum 800 MB/s write stream so every video mode and burst sequence records without dropped frames.
